ENAMELEDWARE.

SPECIFICATION forming part of Letters Patent No. 355,486, dated January 4, 1887.

Application filed July 21, 1886. Serial No. 208,602. (No model.)

To all whom, it may concern: y

'cert-ain new and useful Improvements in Enameled material.

ameled IVares, a description of which is set forth in the following specification, reference being made to,the accompanying drawings, in the several figures of which like letters refer to like parts. y

, My invention relates to a new method of making enameled wares, either fiat, round, or hollow; and it consists, substantially, in superimposing upon each side of afoundation composed of Woven wire-cloth or perforated metal` a suitable enamel, aportion of which willpass entirely through the interstices of the wire, uniting the enamel on both sides, and composing,- substantially, a solid sheet or dish of en- The wire foundation may be in a flat sheet, and in this condition, being covered with the enamel, may be formed into various articles of builders use, such as shingles, gutters, and a variety of other articles, which are at the same time water-proof, rustproof, and nre-proof.

In the drawings, Figure l represents a vase embodying my invention, a portion of the outside enamel, e, being broken away, showing the wire foundation w beneath. Fig. 2 is a vertical section of the same vase, showing the wire foundation centrally embedded in the enamel.

Heretofore enamel of various kinds has been deposited upon a sheetmetal base, generally iron, and the process commonly in use is as follows: The metal intended to be coated with enamel is covered with acid, which is then washed off and a coating of gum is applied, and a glaze which is in the form of a powder is then sifted over the gum, causing the powder to adhere to the metal base, and the articles are then placed in an oven or furnace and heated until the glaze fuses and runs together, forming a continuous enameled surface over such portions of the sheet as have been covered with the powder. This process only puts an enameled coating over a solid base, and the latter under -the action of heat and` cold eX-V pands and contracts unequally with the enamel, cansing it to crack and peel off. In-

. stead of this solid base, I use the flexible wire foundation fw, and the enamel may be either flexible or hard enamel, and the woven wire may be worked or stamped into aA `variety of articles for use-such as pails, pans, and cooking utensils--and after being modeled may then be enameled by my process'. The sheet of wire may be treated in a similar manner to that indicated above and commonly used for the sheetmetal wares. The wire foundation is cleaned with acid, washed, and coated with gum, and the enamel is sil'ted on one side and then siftedv'upon the other,l so as to entirely coat both sides of it, and then baked in a furnace until the glaze fuses, and it will run over both sides of the wire and through the openings, uniting the en amel at thosepoints, and completely covering up the wire foundation, and the article will appear to be only'made of the enamel itself, the wire foundation being completely concealed, as shown in the drawings hereto annexed.

IVhat Iclaim as my invention, andl desire to secure by Letters Patent, is the following: As an article of manufacture, a vase or other article formed of enamelA deposited upon a woven-wire foundation, substantially as and for the purpose described.

In witness whereof IJ have hereunto setmy hand this 14th day of July, 1886.
